Test Kit Calibrations

Mid-West Test Kit Calibration/Repair Services

We are an authorized repair and calibration service center for Mid-West Instrument.  This means we have been trained by Mid-West to calibrate, repair and do warranty work as needed.  Mid-West has manufactured gauges for Apollo, Wilkins, Febco, Flomatic and a few other companies.  

We charge $85.00 + return shipping for calibration regardless of the model.  Usually turnaround time is anywhere from 1-3 business days, depending on the time of year you send it in.  If repair work needs to be done, we will contact you before we do anything to explain the issue and the cost before we proceed, with your approval.

No need to call us or get an authorization to send your gauge to us.  If you send it during the winter months please make sure you get as much water out of the gauge as you can and leave the valves open.  You may send it to us by UPS, FedEx or the US Post Office, whichever you prefer.  Please include this form when sending your test kit to us.  Form for Calibration
